Karelm is right. We've only established that the silk artist in Adelaide may well have been the lady that Adam knew. to properly identify this piece, she will need to see an image of the paperweight, which can't be done by phone.
Karelm, with great respect, I feel a little put upon by your request for someone in Australia to phone this lady. I don't like to make cold calls at the best of times, let alone to someone on the other side of the country.
